The percussion mode is the main method used for the majority of situations. This method uses a drop-hammer to drive a barrel into the ground in 1m intervals to collect a full sample of the geology. The core is recovered in a plastic liner contained inside the barrel which allows inspection of the core in the field.
The percussion method can use 4 barrel sizes, which provide core of 117mm, 102mm, 87mm and 75mm.
If you want to drill:
Opaque liners can be obtained if you require photoluminescence analysis for example.
If you have any questions, would like to discuss any drilling requirements or wish to book the drill team then please speak to Steve Thorpe (Tel: 0115 936 3189) to talk about how the drill team can help. If Steve isn't available then Carl Horabin can help.
